Iran warns US to 'be careful' after Trump threat Iran's chief negotiator Mohammad Bagher Ghalibaf on Sunday warned the United States against making threats at the Islamic republic, vowing that "our armed forces are ready to respond".

We do not take American threats into account," said Ghalibaf, after President Donald Trump threatened to strike Iran over its support for Hezbollah.
